Everytime I open firefox I get a window that opens. Doesn't happen with IE or Chrome

Every time I open Firefox I get another window that opens over the homepage. It is almost blank with a few lines at the top of the page and the words user registration. It has been happening ever since Firefox updated on my computer yesterday, even after uninstalling and reinstalling.

'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Once you get the pop-up, just select "'Start in Safe Mode"''
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the ''Safe mode'' start window.
You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")

Everytime i try to open my Firefox i get a window that pops up asking me which browser i want to use to open it. After choosing Firefox it asks to run a C:/Program Files (x86)/Mozilla Firefox/firefox.exe.

Every time i try to open my Firefox i get a window that pops up asking me which browser i want to use to open it. After choosing Firefox it asks to run a C:/Program Files (x86)/Mozilla Firefox/firefox.exe. But my search bar says file:///C:/Program Files (x86)/Mozilla Firefox/firefox.exe. Never seen anything like this, half tempted to stop using Mozilla for this sole fact. PLEASE someone help me.

Same error message, I disabled tab mix and made sure I only have the newest version of Java, restarted firefox, now it seems to be fine no error yet on Pogo games or pictures upload to ebay which were the biggest problems besides hanging. I had also had disabled AVG secure search yesterday but that did not solve the issue. Now I will try to add back in AVG search...I have very few adds ons, also the note embedded about re- installing a toolbar went away, my old one did not work with FF4, so I installed Yahoo toolbar but the message still did not go away until I applied this fix. Hopes this helps someone..

Hi - for any photo, info in mountain lion shows a different file size than Photoshop does. I've tested with CS3 and CS6 and get the same problem. Doesn't happen with CS3 and OSX10.4 or any previous versions of Photoshop and OSX. Anyone know why?

Hi - for any photo, info in mountain lion shows a different file size than Photoshop does. I've tested with both CS3 and CS6 on 10.8.2 and get the same problem. This doesn't happen with CS3 and OSX10.4 or any previous versions of Photoshop and OSX. Anyone know why?

this one is actually a really rare symptom of a flaky connection to the ipod on a Windows PC. there's more going on in terms of hardware on nanos and 5th gens than in the earlier models ... so if the connection is flaky to precisely the right/wrong degree, itunes will see the ipod, but misidentify it as an earlier version of ipod.
tracking down the cause of the flakiness can be tricky ... as you already know ...
just checking. have you tried connecting with a different (known-good) USB cable? does that seem to have any impact on the rate of occurence of the problem?

New tab opens when I click email link, this doesn't happen with IE or Chrome

I use a specific website for work. When I click a hyperlink on the website that is supposed to generate an email, it also generates a new tab for no reason. This is a waste of time. This also doesn't happen on the same website in IE or Chrome.

Those are extensions for Firefox. You can access the Firefox Add-ons page using one of these methods:
* Ctrl+Shift+a
* "3-bar" menu button (or Tools menu) > Add-ons
In the left column, click Extensions. On the right, enabled extensions are listed alphabetically, with disabled extensions at the bottom.
As a general test for problems caused by any extension, the user can try the same pages/functions in Firefox's Safe Mode. That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using either:
* "3-bar" menu button > "?" button > Restart with Add-ons Disabled
* Help menu > Restart with Add-ons Disabled
(Not all add-ons are disabled: Flash and other plugins still run)
After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (''not'' Refresh).
If the problem goes away, usually that points to an extension as the culprit.
Bear in mind that other aspects of Safe Mode may be more relevant to display glitches (hardware acceleration) or crashes than extensions, but in this case, I'd look at extensions.

When I start up firefox I get two windows that open in succession, one with my 'home page' and the other with the site I am seeking. How do I stop this?

This only occurs when I first open Firefox. Using tabs once I am down to one window does not open a new window.

Do you have both those pages set as your Homepages?

One https site when loading pages driven by aspx Firefox wants to save as a file; doesn't happen in IE or Chrome.

I have been having problems loading https pages from a bank that I have used without issues for a long time. The bank has recently updated their site and this did co-incide with the problem starting. The issue seems to be related to aspx pages. When I click to go to one of the aspx driven pages Firefox wants to download it as a file. If I do that the saved file comes up as HTML text when loaded. No problems when loading the same pages in IE or Chrome. In addition, the bank's older pages did not have this problem with Firefox Betas.

Thanks, that did the trick, although I had to clear the cookie again after loading the site. Having tte cookie there doesn't seem to bother Chrome or IE, so, is this an issue with the way Firefox deals with this site? I have no problem with other banking sites.

Every other time I open a new window or start firefox I get 2 windows in one & nothing happens.

Every other time that I start up Firefox I get 2 windows in one, and nothing happens. Also, whenever I open a new window in Firefox every other window comes up as 2 in one and nothing happens.

When I try to download applications such as Internet Explorer, Yugma, and iTunes in Firefox, I just get a window that says "save" or "cancel", but never one that says "run" so I don't think it's actually installing anything. It shows up in a "download" window, then the icon shows up on my desktop. When I click on it to launch it, it says "open with" and I get the same "save/cancel" window. It's a continuous circle. What am I doing wrong??

What application are you choosing to open the files with?
Because of how integrated it is with windows IE should work. If it's not working, something more widespread could be wrong with your computer that would also prevent other browsers from working properly. Of course we'd love you to stick with Firefox, but you should get help with IE, too.

Using Firefox 4 & Windows 7. Everytime I start Firefox from a shortcut to a website it comes up with the following error 'there was a problem sending the command to the program'. The requested website does load after this. with no problems.

If a shortcut is used while Firefox is already open the error does not occur.

As reported in earlier replies, the annoyance disappeared after I upgraded to Roboform 7.5.6, from 7.5.4.

Hi. Downloads has changed; I cannot open or download attachments. I don't get the window that asked "Open" or "Save" either.

When I receive an attached document (Word or OpenOffice), I click on it. I get a Norton Antivirus window that says it's clear and I click on the yellow Download button. Then nothing happens. 1. I don't get the windows that asked Open? or Save?. 2. The documents are not in the Download folder. 3. I reset the downloads to my Documents folder - nothing appears there either. 4. I search my iMac with the file names, and no results show up.

Hi carrieinholland-
I would recommend reading this Support article on troubleshooting Opening/Download issues:
[[Managing file types]]
Hope that helps.

I recently transfered everything from my emac to another one but now when I try to open iTunes I get the window that states: The file "iTunes Library" cannot be read because it was created by a newer version of iTunes.

I recently transfered everything from my emac to another one but now when I try to open iTunes I get the window that states: The file "iTunes Library" cannot be read because it was created by a newer version of iTunes. The computer I transfered to had a bunch of files on it and I got full ownership of what was already there, so, how do I get to my iTunes library, I do have access as an administrator to the iTunes library (that works just fine) already there and I guess I must have had a newer version ofiTunes on my defunt eMac....

Tell us some version numbers please, of your Mac OS versions and iTunes versions on both computers (two eMacs yes?).

That is a pretty good guess.Try updating the second eMac's iTunes to at least the version that was on the first.

OK, restart in Safe Mode, this will clear some caches. It's possible one or more is corrupt. To restart in Safe Mode when you hear the start up tone hold down the Shift Key until you see a progress bar. Let it fully boot then restart normally and test.
Also I am assuming you have checked Finder - Preferences - General and see what boxes are checked in "Show these items on desktop." You can also mount an item in Disk Utility, simply highlight it and then look in the File menu for Mount.....

Can't open desktop - I get a window that says no application has been found to open the document desktop.

Can't open desktop - I get a window that says no application has been found to open the document desktop.
Any ideas?
Thanks

It may be that a "metadata attribute" called the "bundle bit" has somehow been set on the Desktop folder, such that the system treats it as a "package" rather than as a folder.
To check for this, click on the Desktop, type command-I (Get Info), and look in the General section of the Info window under "Kind". It should say "Kind: Folder" - if it instead says "Kind:package," then I would proceed as follows:
Download and run the utility File Matey. From its "Choose an Object" window, navigate to the Desktop folder and click Choose. In the next window, see if the box for "Has Bundle bit" is checked:
If so, then uncheck it, and click Apply, then Save.
